Nissan, Renault in talks to merge as one company

Nissan and Renault have been tied together as an alliance for nearly 20 years, but now the Japanese and French automakers are discussing whether to merge. Bloomberg, citing unidentified sources familiar with the confidential talks, reports that the idea is to form a larger, single publicly traded company to better compete against giants like Toyota and Volkswagen. It would also mark the end of the alliance that first began in 1999 and also includes Mitsubishi, in which Nissan acquired a controlling interest in 2016. A full merger would help the companies pool resources to develop electric vehicles, autonomous vehicles and car-sharing services. It would involve Nissan giving Renault shareholders stock in the new company, with Nissan shareholders also gaining shares in the new company, Bloomberg reports. The new company would be run by Carlos Ghosn, the current chairman of both companies. But any such merger, as you might expect, would be complicated, in part by geopolitics. The French government owns a 15-percent stake in Renault, and both the French and Japanese governments might be reluctant to let go of their respective home-grown brands. Currently, Renault owns a 43-percent stake in Nissan, while Nissan owns 15 percent of its French partner. Reuters reported recently that Ghosn proposed buying most of the French government's stake in Renault as part of plans for a closer tie-up. The Renault-Nissan-Mitsubishi alliance already has been working to establish a $200 million mobility tech fund to invest in startups, a reflection of how seismic changes in the auto industry have left many legacy companies scrambling to stay current. Nissan in 2016 paid a reported $2.3 billion to acquire 34 percent of Mitsubishi in order to share platforms, technology, manufacturing and other resources.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

Road & Track names its 2013 Performance Car of the Year

Road & Track recently staged its first annual Performance Car of the Year test, pitting 13 new and updated performance cars against each other on track, then graduating the top six to a road test before picking a winner. Additionally, the magazine staff picked the best automobiles of the year in eight categories.
But first, let's cover the PCotY segment. Here's the list of cars brought to the comparison test: Audi R8 V10 Plus; BMW 435i; BMW M6 Competition Package; Chevrolet Corvette Stingray Z51; Ferrari F12 Berlinetta; Ford Fiesta ST; Jaguar F-Type V8 S; Jaguar XFR-S; Mercedes-Benz E63 AMG S-Model Wagon; Mercedes-Benz SLS AMG Black Series; Mini John Cooper Works GP; Nissan GT-R Track Edition; and Porsche Cayman S.
To find out the results of the comparison, head over to Road & Track's website or check the press release below, where you'll also find the magazine's top-rated vehicles in eight categories. Want more? Head over to the 2013 PCotY hub. But before you do that, take a stab at guessing the winner of PCotY (we'll give you one hint: it isn't a Porsche).
